A preform for fabricating a wheel rim and a method of making a preform is provided. The preform includes a main section and at least one secondary section, each section being formed from composite materials, such as triaxially braided composite material that includes fibers oriented in at least three directions. The main section forms at least part of a lateral section of the preform and the secondary section forms at least part of a radial portion of the preform, the radial portion of the preform being generally perpendicular to the lateral section of the preform. The preform is fabricated from a plurality of composite layers, at least some being custom composite layers having a plurality of axial fibers interwoven intermittently with substantially consistent first and second sets of biased fibers. In some embodiments, the preform is initially fabricated in an intermediate configuration prior to being moved to a final configuration.

Hybrid fibrous composite materials incorporating at least two different fabric components and a multicomponent adhesive system for adhering the fabric components together. The adhesive system enhances the bond strength between the fabric components, which would otherwise easily delaminate from each other and peel apart. The components of the adhesive system bond strongly to each other as well as to the fabric elements.

Multilayer composite materials combining a low tenacity nylon fabric with a fabric formed from high tenacity fibers. The fabrics are bonded with a compatibilizing adhesive system that achieves a peel strength of at least 1.5 lbs/inch. The nylon is colored with a camouflage pattern and the high strength fabric is colored with a color that does not stand out relative to the camouflage pattern. The composite materials are used for forming vest covers and plate carrier materials, particularly webless plate carrier materials having slots for hanging modular accessories.

An electric machine comprising a stator (50), a rotor (29) radially inward of the stator and comprising a plurality of surface permanent magnets (44) and a rotor sleeve (46) surrounding the rotor. The rotor sleeve comprises a plurality of layers of fibre reinforced matrix material (56, 60). The rotor sleeve defines a rotor sleeve radius to radial thickness ratio (r:t) between 20 and 40, and the electric machine has a maximum rotor rotational speed greater than 15000 RPM.

A composite panel including a multilayer laminate with a plurality of central plies of fibre reinforced resin matrix composite material, wherein at least one of the central plies includes a first fibrous layer of a plurality of non-woven carbon fibres which are substantially randomly oriented, and a rear reinforcement layer which is integrally moulded with the central multilayer portion the reinforcement layer being comprised of a rear ply of fibre reinforced resin matrix composite material, wherein the rear ply includes a second fibrous layer of a plurality of continuous fibres which extend continuously from at least one portion of a first edge of the rear ply to at least one portion of an opposite second edge of the rear ply.

A multilayered sheet is described. The sheet comprises a first layer comprising a polyolefin having a melting temperature, a storage modulus (G) greater than 100,000 psi (690 MPa) at ambient temperature, and a glass transition temperature less than ambient temperature; and a second layer comprising a polymer having a glass transition temperature greater than ambient temperature.

Multilayer composite materials having a camouflaged appearance. More particularly, camouflaged tactical vest covers having slots for the webless attachment of accessories. An easily colored outer fabric is provided with a colored camouflage pattern and backed with a non-colored high tenacity fabric for enhanced durability. A colored intermediate adhesive is employed to maintain a camouflaged visual appearance without the added complexity of dying the high tenacity fibers of the backing material.

A lithium-ion battery outer package material, provided with: a base layer, and a first adhesive layer, a metallic foil layer, a corrosion prevention treatment layer, a second adhesive layer, and a sealant layer sequentially layered on one of the surfaces of the base layer. When a tensile test (a sample of the substrate layer is stored for 24 hours in a 23 C. and 40% RH environment; a tensile test is subsequently performed in a 23 C. and 40% RH environment with the specimen width being 15 mm, the distance between gauge points being 50 mm, and the tensile speed being 100 mm/min; and the tensile elongation and tensile stress of the specimen are measured) is performed, the tensile elongation in a first direction, which is either the TD direction or the MD direction of the sample, relative to the length of the sample is from about not less than 50% to less than 80%, and the tensile stress in a second direction, which is perpendicular to the first direction, is from about not less than 150 to 230 MPa.
